HILARY & AARON
#RelationshipGoals wasn't even a thing when they dated in the early 2000s – but that's probably not the hashtag we'd use to describe Carter's 2014 attempt to woo back his former teenage sweetheart on Twitter. "Him reaching out through social media? It's ridiculous," Duff shot back in a March 2015 Cosmopolitan interview. It's time to stop living in the past: "Keep it between text messages," she added.

TAYLOR & JOHN
We already knew Mayer wasn't exactly singing along with the Swifties to "Dear John," the songstress's rumored ode to their romance. Still, we stayed strong believing that someday, somehow, they'd reunite for a duet … but we'll have to stick to 1989 on repeat for now. "You can see me at the Grammy Awards doing what I do best," he joked in February 2015. "Being avoided by Taylor Swift."

KATY & RUSSELL
Theirs was a fairy-tale romance, celebrated with an ultra-private and exotic Indian wedding in 2010 before ending abruptly 14 months later. And while Brand said he'll , the singer did not find the humor in the British comedian's method of ending their marriage. "Let's just say I haven't heard from him since he texted me saying he was divorcing me December 31, 2011," said Perry, who's currently dating John Mayer, in a revealing July 2013 Vogue interview.

KRISTEN & ROBERT
Though the couple of three years reconciled in October 2012, following Stewart's cheating scandal with her Snow White and the Huntsman director, their relationship came to an abrupt end when Pattinson failed to attend a 2013 birthday celebration thrown by Stewart. And days later, on May 19, the British actor moved out of her Los Feliz, Calif., home. Adding insult to injury? The pickup truck he used to make his getaway looked suspiciously like Bella Swan's onscreen ride. "The hardest part was talking about it," Pattinson, who's getting serious with FKA twigs, later reflected in 2014.

NINA & IAN
Just as their TV counterparts found love on The Vampire Diaries, Dobrev and Somerhalder called it quits in May after several years of dating. "A THOUGHT FOR TODAY: People change and forget to tell each other. -Lillian Hellman, playwright (1905-1984)," the now-engaged actor cryptically Tweeted before ultimately deleting the Tweet. (But don't worry – they keep it pretty friendly.)

TOM & KATIE
When Holmes filed for divorce in June 2012, five days before her megastar husband's 50th birthday, no one was more surprised than Cruise, who "had no idea this was coming," a source told PEOPLE. The actress, meanwhile, had spent weeks orchestrating the split, including moving into a separate N.Y.C. apartment, seeking counsel from her lawyer father and switching cell phones.

DAVID & RYAN
Following 10 years together, My Fair Wedding host Tutera filed to end his domestic partnership with Jurica in May – only two months before the birth of their twins via a surrogate. In response, Jurica's papers cited Tutera's sex addiction as the reason for the split, which the WE tv star called, "baseless and untrue … I believe them to be fabrications of a desperate individual in order to gain a legal advantage in our separation."

PORSHA & KORDELL
The Real Housewives of Atlanta star learned the hard way about gamesmanship when her NFL player husband Stewart filed for divorce in March 2013 – over Twitter. "When you're married you definitely feel like you have the ability to communicate with your mate enough for them to come in and say, 'Hey, we're going to get a divorce.' But that didn't happen," she told PEOPLE. "I found out about [the divorce filing] on Twitter, which was surprising. I'm still in total shock."

HEIDI & SEAL
Seven months after announcing her from husband Seal in January 2012, the Project Runway host stepped out with the family's bodyguard, Martin Kirsten. "Whilst I didn't expect anything better from him, I would have thought that Heidi would have shown a little more class and at least waited until we separated first before deciding to fornicate with the help," Seal quipped to TMZ, though he later clarified he did not mean to imply Klum, who's now dating Vito Schnabel, had been unfaithful.
